Coal and Biomass Blending is Important - Hot Topic Hour June 10, 2010
The four speakers yesterday agreed that coal and biomass blending is an important opportunity to reduce costs and meet environmental regulations.
James R. Mooney, Owner JRM Energy Consulting provided insights on software systems which allow tracking of different types of coal in the incoming shipment, the bunkers and then through the system.
Kevin Gordon, Applications Engineer Thermo Scientific Materials & Minerals, discussed the use of analyzers to effectively blend coal to optimize boiler efficiency in U.S. power plants. The analyzer can measure chlorine along with Btu and a number of elements.
Craig Vogel, Project Manager at CH2M Hill, discussed the effects of coal blends on plant performance. The opportunity to burn low Btu coals during off peak periods can help reduce total costs.
Jeffrey (Jeff) M. Russell, Engineer at MPR Associates, Inc., showed how coal blending provides operating flexibility. On-site blending provides more flexibility than off-site blending.
Coal blending decisions will be strongly impacted by the upcoming MACT rules. Some of the flexibility built into 30 rolling averages for emission constraints allow a blending scheme that changes if you have a MACT rule that has hourly limits. There was a discussion as to whether with blending of coals you would be able to determine the inlet mercury and therefore prove a 90 percent reduction. It was pointed out that New Jersey allows proof based on measuring the inlet to the control device and the outlet. However, this could make it tougher for the utility. Lets say 10 percent of the mercury is captured prior to the measurement point. With the New Jersey rule, the plant would not obtain credit for this removal and would still have to remove 90 percent of the remaining mercury. The speakers agreed that the coal blending techniques would serve well when most plants will be faced with adding biomass to reduce the carbon footprint.
